Celtic punk rockers the Dropkick Murphys have donated over $300,000 (£193,548) to the victims of the Boston Marathon bombings after raking in the cash through multiple fundraising efforts. The Rose Tattoo hitmakers, founded by bassist/vocalist Ken Casey, were determined to do all they could to help those affected by the horrific April (13) attack in their native Massachusetts and immediately created a custom T-shirt to sell online to raise money for the cause. They also recorded a special EP featuring a collaboration with Bruce Springsteen and hosted a series of benefit gigs, with all profits going to Casey's The Claddagh Fund, an organisation which serves the most "vulnerable". The bandmates have since handed over the six-figure sum to aid more than 60 victims of the bombings, visiting many in person last week (ends05Jul13) to hand over the much-needed funds to assist with medical bills and related expenses. Casey says, "Every single person we had the pleasure of meeting expressed a positive attitude and an incredible sense of perseverance as they work hard to return to the lives they enjoyed before the tragic day in April. "We were humbled by the kindness of our friends and fans who got behind this cause with so much heart and passion, it was truly an honor to be able to represent them and contribute, even if in a small way, to help these inspirational individuals." Three people were killed and another 264 were injured when brothers Dzhokhar and Tamerlan Tsarnaev allegedly planted two pressure cooker bombs near the finish line of the annual race in Massachusetts on 15 April (13). Tamerlan was killed in a shoot-out with police following a manhunt in the days after the bombing, while his 19-year-old brother Dzhokhar was captured and pleaded not guilty to 30 counts, including use of a weapon of mass destruction to kill, during his arraignment hearing in a Boston federal court on Wednesday (10Jul13). The Dropkick Murphys' donation announcement comes just a day after Styx, Ted Nugent and REO Speedwagon were revealed to have helped raise $108,000 (£69,677) for the Boston One Fund, which was launched to provide financial aid to those affected by the attack.
